I need a good chocolate fondue recipe. I'd also love to hear about the best way to make cheese fondue. About 50% of the time I make cheese fondue, it never mixes well. I end up with lumps of melted cheese in an oily-wine broth.

One of the things that is important to a cheese fondue is that you have enough acidity to denature the proteins in the cheese. If it's not working for you, make sure to add some add lemon juice with the wine. Also, it's pretty much crucial that you add some cornstarch or potato flour to keep the cheese from separating after it's melted.

As for dessert fondues, my favorite is the classic toblerone fondue. Warm 6 tablespoons of cream, then melt 10 oz of toblerone into that. Finish off with a couple of tablespoons of cognac at the end.

Chop the chocolate and put it in your fondue bowl.
Heat whipping cream almost to boiling.
Stir liqueur into cream.
Pour cream over chocolate and let it sit a bit while you light the flame underneath.
Stir chocolate and cream until smooth.

I generally prefer a bitter chocolate for fondue since I'll be dipping sweet things into it.
